Abstract
Contemporary shifts in global and national security frameworks underscore the pressing need to reevaluate legal mechanisms governing perimeter security. Despite the integration of intelligent surveillance technologies in the Republic of Kazakhstan, a unified and systematic legal framework remains absent. This gap manifests in terminological ambiguity, regulatory fragmentation, overlapping institutional responsibilities, and underdeveloped evidentiary mechanisms. The objective of this research is to conduct a comprehensive legal assessment of Kazakhstan's perimeter security legislation and to propose a reform-oriented legal model grounded in risk-based categorization, drawing on international best practices. The study employs a multidisciplinary methodology that includes formal legal analysis, comparative legal research, statistical evaluation, and content analysis. The empirical base consists of official law enforcement statistics, judicial rulings, regulatory acts, and data from pilot security projects. The findings reveal that perimeter security has not yet been conceptualized as an independent legal institution within the national framework. Technical surveillance tools lack recognized evidentiary status, and there is no structured legal stratification based on threat levels. The study thus advocates for the development of a multi-tiered legal model, the formal recognition of technological evidence, and the delineation of institutional competences. These conclusions offer theoretically grounded, practically relevant recommendations to modernize national legislation, enhance law enforcement institutions' procedural capacity, and foster the integration of advanced security technologies into the legal domain.
